The SB-700 has a "distance priority manual mode" (GN on the mode switch) that lets you configure the distance to the subject and have the flash power set based on that. It's still manual in the sense that you control exactly what results you get, but will assist you with some of the maths involved.


With manual flash and camera in manual mode, I think you already hit on one method of "metering" ... trial and error. Take a picture, chimp, adjust. Repeat until lighting is what you want. The other way is to use a handheld light meter.


When using regulable flashes or countinuous lamps, the lightmeter does not tell the photographer what aperture to use, instead it tells which aperture the current lighting is set up for. The photographer first decides what aperture to use, a suitable ISO and exposure time. The meter is then used to find a flash or lamp setting that is good for the aperture ...


It shouldn't, PDAF occurs before any metering adjustments are made because the quality of focus is directly dependent on the available light. Focusing should occur with the aperture wide open before anything is stopped down.


Yes, a flashmeter only gives aperture. The shutter speed on the camera merely has to be long enough to ensure the film or sensor are uncovered for the duration of the flash (1/50 sec for a Leica M3, 1/250 for modern SLRs and up to 1/500 for a leaf shutter) and doesn't affect the exposure, assuming ambient light is insignificant compared to the flash output, ...


You've only got the three variables to work with -- ISO, aperture, and shutter speed. When shooting in a studio environment, shutter speed doesn't really matter because you're relying upon the lights and their limitations, so you often need to work at 1/60 sec. You input your desired ISO into the light meter, and take a reading. The only variable left is the ...


When we talk about flash photography; this is because the shutter speed does not contribute to the exposure from the flash. A flash will output a burst which last maybe 1/1000s, so changing the shutter speed won't affect the exposure from the flash but form the other continuous light sources. And since the light meter used in the first video you linked ...


You would let the light meter choose the aperture if you did not care about that choice. That's the short answer. I think you are thinking about it correctly. You need to make a choice of the aperture for DOF reasons or perhaps you care more about a specific shutter speed to capture motion (or not) the way you want. But the light meter has to tell you ...
